Report on Management’s Responsibility for Financial Statements

Our management is responsible for the preparation, integrity and fair presentation of our published financial statements. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include amounts based on informed judgments made by management.

We believe it is critical to provide investors and other users of our financial statements with information that is relevant, objective, understandable and timely, so that they can make informed decisions. As a result, we have established and maintain systems and practices and internal control processes designed to provide reasonable, but not absolute, assurance that transactions are properly executed and recorded and that our policies and procedures are carried out appropriately. Management strives to recruit, train and retain high quality people to ensure that controls are designed, implemented and maintained in a high-quality, reliable manner.

Our independent registered public accounting firm audited our financial statements and the effectiveness of our internal control over financial reporting in accordance with standards established by the Public Company Accounting Oversight Board (United States). Their report appears on the next page within this Annual Report on Form 10-K.

Our Board of Directors normally meets at least eight times per year to provide oversight, to review corporate strategies and operations, and to assess management’s conduct of the business. The Board of Directors also schedules additional meetings on an as needed basis. The Audit Committee of our Board of Directors is composed of at least three individuals all of whom must be “independent” under current New York Stock Exchange listing standards and regulations adopted by the SEC under the federal securities laws. The Audit Committee meets regularly with our internal auditors and independent registered public accounting firm, as well as, management to review, among other matters, accounting, auditing, internal controls and financial reporting issues and practices. Both the internal auditors and independent registered public accounting firm have full, unlimited access to the Audit Committee.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate systems of internal control over financial reporting as defined by Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2024.

In making this assessment, management used the criteria set forth in Internal Control-Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management concluded that our internal control over financial reporting was effective at a reasonable assurance level as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, our independent registered public accounting firm as stated in their report which is included below within this Annual Report on Form 10-K.
